Cluster without shared disk, or over shared over NFS

[Marcos Monge]

Sorry, there is an error in the step 3. To obtain the IQN (iscsi uniq
identifier) of each linux server, you must start the
/etc/init.d/iscsi, and look the /etc/initiatorname.iscsi file, that
have the iqn asigned to the linux server.

Best regards
marcos
